so say if i wanted to do a tapped harmonic on the 5th of the G, then i wud have to hold down 5 on the G and 15th On the same 6, and fret them both.. one after the other.. its sound's..like a normal tapped 15th note.. no harmonic??

ok im fretting the C on the G which is the 5th fret.. and the 17th fret which is the higher C, i was already doing that i just made a mistake when writing it up, but im still not getting a harmonic sound..
